MATTRESS Filed Nov. 18, 1964 INVENTOR MICHAEL QANSON United StatesPatent 3,256,535 MATTRESS Michael D. Anson, 2311 Raleigh Lane,Louisville, Ky. Filed Nov. 18, 1964, Ser. No. 412,046 5 Claims. (Cl.5-351) This invention relates to inner spring mattress constructionsand, more particularly, to the design of the frame and the cover incombination therewith.

The particular construction disclosed herein provides a means forattaching the cover in a centrally located position between the top andthe bottom of the mattress whereby the cover is held positively inposition with relation to the top and bottom of the mattress.

It is, accordingly, an object of the present invention to provide animproved inner spring mattress construction.

Another object of the invention is to provide a combination mattresscover and border wire construction.

A further object of the invention is to provide an improved inner springmattress having a top border Wire, a bottom border wire, and anintermediate border wire having coil springs and a cover and means forattaching said center border wire to said cover.

With the above and other objects in view, the present invention consistsof the combination and arrangement of parts hereinafter more fullydescribed, illustrated in the accompanying drawing and more particularlypointed out in the appended claims, it being understood that changes maybe made in the form, size, proportions, and minor details ofconstruction without departing from the spirit or sacrificing any of theadvantages of the invention.

In the drawing:

FIG. 1 is an enlarged partial view of the spring and border wireconstruction of the mattress according to the invention; and

FIG. 2 is a view similar to FIG. 1 showing a cover and padding in placeon the springs.

Now with more particular reference to the drawing, the mattressconstruction shown is made up of the usual coil springs 10, top borderwire 11, bottom border wire 12, and intermediate wire 13. The top,bottom and intermediate wires are provided with helical wires 14 whichare wrapped around the top, bottom and intermediate border wires andeach are twisted around a turn of the helical support springs at 20, 21and 25 of the top turn 33, intermediate turn 28 and lower turn 35respectively of the coil springs.

The top border Wire and bottom border wire may be formed into agenerally rectangular frame and the helical support springs 10 at eachcorner will be attached to both the front and the end portion.Therefore, one of the coil springs 10 is disposed directly in eachcorner of the mattress. The top and bottom border wires each define aframe slightly larger than border wire 13.

The intermediate wire 13 will be connected to the cover part 15 by meansof hog rings 18 which will extend through the cover part 15 after it hasbeen pulled taut and around the center wire 13 and the center coil ofthe coil spring 10. These hog rings 18 will be attached to each coilspring and the rings will be placed at spaced portions completely aroundthe outer periphery of the mattress.

After this is completed, the mattress is inverted and the cover part 30is pulled taut in the same fashion overlapping cover part 15 and thecover parts 30 and 15 will be hog ringed to the center wire and theoutside coil springs by means of rings 43. Thus, the cover parts 15 and30 will be fixed to the center wire 13 as well as to the center turn ofthe coil springs adjacent thereto.

3,256,535 Patented June 21, 1966 ice Since the center wire 13 isslightly inside a plane passing through the margin of the border wires11 and 12, the cover parts 15 and 30 will be held slightly inside theupper and lower marginal parts.

The mattress may have the usual felt padding 16, sisal pad 17, and covermaterial 19 over the top as well as the flange cover material 15 whichmay be sewed to the cover material 19 by seam 40. The bottom covermaterial 41 may likewise be sewed to the flange cover material 30 in thesame fashion.

The foregoing specification sets forth the invention in.

its preferred practical forms but it is understood that the structureshown is capable of modification within a range of equivalents withoutdeparting from the invention which is to be understood is broadly novelas is commensurate with the appended claims.

The embodiments of the invention in which an exclusive property orprivilege is claimed are defined as follows:

1. A mattress comprising a top border wire,

a bottom border wire spaced from said top border a center wire betweensaid top border wire and said bottom border wire,

helical support springs each having its lower end disposed generally ina plane with said bottom border wire and its top disposed in a commonplane with said top border wire, said border wires being in the form ofloops tangent to the turns of said helical springs,

said center wire being in the form of a loop slightly smaller than saidloop defined by said top and said bottom border wires,

means attaching said coil springs to said top border I wire and to saidbottom border wire,

sheet like cover material disposed over said mattress,

a part of said cover extending from said top border wire to said bottomborder wire,

and means connecting said cover. to said center wire.

2. The mattress recited in claim 1 wherein said means connecting saidcover to said center wire comprises hog rings extending through saidcover material and around said center wire.

3. The mattress recited in claim 2 wherein helical wires are disposedaround said top, bottom and center wires,

' one turn of each said helical wire passing around a turn of each saidhelical support spring.

4. The mattress recited in claim 1 wherein said part of said coverextending from said top border wire to said bottom border wire isdivided into two cover parts comprising a first cover part and a secondcover part,

said first cover part being connected to said center wire with hogrings,

and said second cover part overlying an edge of said upper end disposedin a plane defining said rectangle of said top border wire,

and a large turn at the lower end disposed in a plane of said rectangledefined by said bottom border wire,

each said helical support spring having a relatively small turn betweensaid large end turns,

a helical wire around each said border Wire,

each said helical wire around said border wire passing around a turn ofeach said helical support spring,

a sheet like cover over said mattress disposed in engagement with eachsaid border wire,

and hog rings extending through said cover and disposed around saidintermediate border wire whereby the side edges of said cover at saidintermediate border wire are held inward of said top and bottom borderWires.
